sum 10F 2 INVENTOR. JOHN J Dew/v PATENTEIJJUL 41972 SHEET 2 0F 2 INVENTOR. J0 HN J 1M w/v CONSTRUCTION SUPPORT MEANS BACKGROUND OF THE INVENTION 1 Field of the Invention The present invention relates to construction, fonns and scaffolding and more particularly pertains to construction aids for supporting brackets, scaffolds and the like from vertical walls which may later be disassembled and reused.

2. Description of the Prior Art In the construction field, it has been the general practice to construct separate scaffolds along form walls and such, when the height thereof exceeds approximately 6 feet. In the event the wall is of an extended height it becomes requisite to layer the scaffolding. Thus, not only the separate construction costs must be included but the time consumed in constructing and removing the scaffolding are definite limiting factors involved. The present invention makes use of existing elements and can be readily applied and removed with a minimum expenditure of both time and expense.

SUMMARY OF THE INVENTION The general purpose of this invention is to provide a structural aid or apparatus for supporting a scaffold that has all the advantages of similarly employed prior art devices and has none of the above described disadvantages. To attain this, the present invention provides a unique support bracket arrangement for attachment to an existing member or for use with an added member. The support aid includes a plate formed with a central aperture and having extending outwardly thereof and affixed thereto a hollow cylindrical support member which terminates in a reinforced end portion. The support is provided with upstanding pin members for coaction with mating holes in the structure to be supported, as a scaffold bracket or the like.

An object of the present invention is to provide a reusable support structure which is simple, inexpensive, reliable, easily assembled and disassembled.

Another object is to provide a support bracket which can be attached to existing erection members without interference and may be located at selected heights.

Still another object is to provide a support bracket aid for use with and on concrete forms and the like.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an embodiment made in accordance with this invention;

FIG. 2 shows in cross-section the embodiment of this invention as applied to a structure using a tie rod or the like;

FIG. 3 shows in perspective the embodiment of the invention as applied to the back side of an erection form;

FIG. 4 shows in perspective a scaffold bracket adapted to be used in conjunction with this invention; and,

FIG. 5 shows again in perspective the complete scaffold support structure as applied to a vertical form.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the illustrated embodiment of the invention of FIG. 1, the structural aid includes a plate-like rigid member of high strength material such as steel which is provided with a central aperture 11 therethrough, and a plurality of holes 12 for attachment to other members where necessary. Extending outwardly thereof is a hollow cylindrical support member 13 whose bore 14 is aligned with the aperture 11. The support 13 is again of a rigid high strength material and, if steel, it is welded directly to the plate member 10 like a stud at weld joint 15 but for support its end 16 (see FIG. 2) extends into the plate and may be welded on the opposite side or reinforced in any suitable well. known manner. The free end 17 of the support 13 is enlarged as at 18 so as to readily absorb the wear and abuse incident in heavy construction. This enlarged end 18 is also provided with a lateral threaded opening 19 for receiving therein a locking screw. Intermediate the ends of the support and rigidly affixed thereto are a plurality of upstanding vertical pins 20 and 21.

FIG. 2illustrates the erection aid 22 as supplied to a construction form wall 23 which is supported in part by a vertical stud 24. In applying the aid 22 the form wall is drilled so as to provide a hole 25 and a securing tie 26 or a pencil rod as it is known in the trade, is passed therethrough and formed about the stud 24 and secured thereto by a. nail 27 driven through the tie end 28 into the stud. The aid 22 is then passed over the tie 26 which is disposed within the support bore 14 and the plate member 10 abuts the form wall and may be nailed thereto if necessary. The end 29 of the security tie 26 is bent so as not to present a danger and screw 30 in threaded opening 19 locks the aid on to the tie 26.

FIG. 3 again shows a construction form wall 23' through which passes a snap tie 31, a common element in concrete forms employed to properly space the form walls, among other uses. Rear vertical stud 32 supports the wall with horizontal walers 33 and 34 which are nailed directly into and abut the vertical studs. In order to provide a support on this side of the wall 23', the aid 22 is disposed with the support member 13 resting on the upper Waller 33 and the plate 10 nailed to and tightly abuting short stud 35 which is nailed to the wall as a spacer. The plate 10 may additionally be nailed to the short stud 35 so as to prevent canterlevering of the aid 22. Thus the support aid is itself adequately held and supported by both the walers and the stud without the necessity of any central rod support. It should be noted that although pin 21 is above the waler 33, pin 20 is free to provide its function as well as there being a sufficient free length of support member 13 available.

Although a large variety of structures could be supported by the instant, above described aid, one such typical unit, a scaffold bracket 36 is shown in FIG. 4. The bracket 36 can best be constructed of angle iron or other suitable elements with a horizontal arm 37 affixed to depending perpendicular arm 38 as by rivets 39 or directly welded thereto. In order to provide the necessary support strength cross-tie 40 rigidly connects the arms near their far ends and is riveted to each as at 41 and 42. The free end 43 of arm 37 on which the scaffolding will rest is provided with an upstanding portion 44 so as to prevent the scaffolding from moving laterally 0B the bracket. Likewise, one wall 45 of the depending arm 38 extends upwardly above the horizontal arm 37 and has its upper end 46 bent inwardly into a curved bearing plate 47 so as to mate with and abut the support member 13 of the aid 22 when placed thereon. Hole 48 in the bearing plate 47 will locate the bracket on the aid by cooperating with one of the upstanding pins. Angle wall 49, abuts either the form wall or the edge face of the waler since the hold 48 position relative to either pin can be readily fabricated for this specific use.

In the illustration of FIG. 5 another portion of the form wall 23" is supported by vertical studs 50, 51 and has passing therethrough, as is customary, a plurality of snap ties, one of which, 52, has affixed thereto the support aid 22. The aid is positioned about the snap tie which is disposed in the bore of the support 13 with its terminal washer 53 extending beyond the end of the member 13. Disposed intermediate thereof is locking wedge 54, a conventional construction unit, which is placed over the snap tie washer via the enlarged opening 55. Since the slot 56 is smaller than the washer 53 and the wedge thickens away from opening 55, the entire structure is locked in position by movement of the wedge toward the right. The bracket 36 is then placed with bearing plate 47 over the support aid as shown and an excellent removable scafiold is provided.

It should be understood, of course, that the foregoing disclosure relates to only a preferred embodiment of the invenbeing enlarged and formed with a lateral threaded opena uni t to be supported and said unit being provided with:

an upwardly extending portion terminating in,

5 a bearing plate having an inward curvature for resting on and abutting said support member and provided with an opening for receiving at least one of said pins.
